The Europe PMC OAI service, (Europe PMC-OAI) provides access to metadata of all items in the Europe PMC archive, as well as to the full text of a large subset of these items.
Europe PMC-OAI is an implementation of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), a standard for retrieving metadata from digital document repositories. Visit the Open Archives Initiative site for more information about the protocol and other activities of the OAI group.
PMC-OAI supports OAI-PMH version 2.0. It does not support earlier versions of the protocol.
Most of the items in this archive are copyright protected, with copyright held by the author(s) or the depositing journal. In general, the OAI service cannot be used to retrieve the full text of articles in PMC. The only exceptions to this policy are for articles that are in the public domain and those that are made available under an Open Access provision (see the PMC Open Access subset for specifics).
